WordPress в подкаталоге с Nginx

Независимо от того, что я делаю, мой сайт WordPress работает отлично, включая все постоянные ссылки, но я не могу получить доступ к области wp-admin. Всякий раз, когда я пытаюсь это сделать, я получаю ошибку 404. У меня WordPress установлен в его собственный каталог, называемый просто «wordpress». Вот мой файл конфигурации:

    server {
    listen 443 ssl;
    server_name my-domain.com;
    root /home/wp-user/my-domain.com/public;

    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

    index index.html index.htm index.php;

    charset utf-8;

    # Deny all attempts to access hidden files such as .htaccess, .htpasswd, .DS_Store (Mac).
    # Keep logging the requests to parse later (or to pass to firewall utilities such as fail2ban)
    location ~ /\. {
        deny all;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/my-domain.com-error.log error;

    # Deny access to any files with a .php extension in the uploads directory
    # Works in sub-directory installs and also in multisite network
    # Keep logging the requests to parse later (or to pass to firewall utilities such as fail2ban)
    location ~* /(?:uploads|files)/.*\.php$ {
        deny all;
    }

    # WordPress single blog rules.
    # Designed to be included in any server {} block.

    # This order might seem weird - this is attempted to match last if rules below fail.

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    }
